working parts will be relieved from excessive.

pressures which might otherwise distort the mechanism.

The invention is designed more especially w as an improvement onmy Patent 1,434,741,

and among its other advantages is the simplification-o structure, ease of assembly and separation, and increase in efficiency. A

With the foregoing and otherobjects in view which .will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention may` be made within the scope of what isyclaimed without departing from' the .spirit of theinvention.

In 'the accompanying drawings the preferredvform of the invention has been shown.

In said drawings Figure 1 is a central vertical section, they drive shaft being shown in elevation.

Figure 2 is a plan view, parts being broken away.

Figure 4 is a section on a reduce taken on the line 4 4, Figure 3.

Referring to the figures by characters of reference, 1 designates a substantially globular casing formed of separate sections 2and 3 provided with flanges 4, whereby they can be held together. detachably by means of bolts 5. A housing 6 is formed by extensions of the sections 2 and 3, and is provided with ports 7 and 8.

' Bonnets 9 are secured to the casing 1 atl diametrically opposed points, and carry bearings 10 and packings 11' through whichis 'extended a drive shaft 12. J

The housing 6 is provided with a partition 13 between the ports 7 and 8 and in this partition is a take-up plate 14 adjustable by a screw 15 and adapted to engage the outer to surface of'a wabble-ball 16. This ball has Figure 3 is a section on line 3-3,Fi(gure 2.. scale diametrically opposed conical recesses 17 and 18, the apices of which meet at the center of the ball while the central axes of the recesses coincide. An opening 19 connects the inner ends of the' recesses and is flared 55" towards its ends.

The shaft 12 extends' through the conical recesses and through openin 19 and has opposed cones 20 and 21 keye thereon as at 22. The longitudinal axesof the cones coincide as indicated by the dotted line .23, and are obliquely disposed relative to the axis of rotation of shaft 12.-

The ball 16 is4 provided midway between its recesses 17 and 18 with an annular groove 55 24, .the walls of which diverge outwardly from a rounded core 25 formed by the center of the ball. v l

A stator in the 'form of a split disk 26, is

clamped at its margin between the sections 2 70 and 3 and is contained in the. groove The sections of the disk bear at one end against an abutment 27 carried by the ball and intersecting groove 24. z l

A central opening 28 is formedin the disk 7,5 and the core 25 of the ball -rocks therein. In the wall' of this opening vis a groove 29 holding a split sealing ring 30. Springs 31A seated in groove 29 act to hold the sealing ring inintlmate contact with the core 25.

Balls 32 arecarried by the wabble-ball 16 and Hprovide bearings for the cones 20 and 21. Wear rings 33 are seated inthe sections 2 and 3 for engagement by ball 16.

The walls of groove 24: are sopositioned 85 relative to the faces of disk 26 that when the ball'is given a wabble motion the walls will have a'moving contact with upper and lower facesV of the disk at diame 'cally op-A posed points respectively. This wabble mor .90 tion will be imparted r-by the vobliquely dis' posedcones rotating with shaft 12. The upper wallyof the groove in the ball will ltrap water or other liquidv received from port 7 at one side of partition 13 and abutment 27, 95 forcing. it around the shaft and along one face of the disk 26 until the other port-8 is reached. The other wall will similarly trap fluid on the other face of the disk. Thus during one rotation of the shaft, there will A$1.36*

be two expulsions of uid by the co-operating surfaces of the disk 26 and groove 24.1. It

' will be'notedthat port 7 can supply iuid to `both sides of disk 26 while port 8 can receive fluid from both sides thereof. The ball 16 can be provided with packing rings as shown, for example, at 34.

What is claimed is:

1. A pump' including a casing, a stator therein, a wabble ball having an annular groove in which the stator is seated, an inlet port and an outlet port opening into the groove at each side of the stator, an abutment between the inlet and outlet ports, a shaft rotatable with the ball, and means carried by the shaft for imparting` a wabble motion to the ball relative to shaft and stator, said means includingr opposed cones rotatable with the shaft and having alining axes obliquely disposed relative to the shaft, there being recesses in the ball providing seats for the cones. t

2. A pump including a casing, a stator therein. a wabble ball having an annular groove in which the stator is seated, an inlet' port and an outlet port opening into the groove at each side of the stator. an abutment between the inlet and outlet ports, a shaft extending through the ball, and means carried by the shaft for-imparting a wobble motion to the ball relative to shaft and stator, said means including opposed cones rotat-s able with the shaft and having alining axes obliquely disposed relative to the shaft. there being recesses in the ball providing seats for the cones, and anti-friction bearings be tween the cones and their seats.

3. A. pump including a easing. opposed cones mounted for rotation in the easing;

about an axis obique to the axis of the cones,

a wabble ball in the casing having seats for the cones and an annular groove, a stator extending around the ball and lseated in the groove, an inlet port and an outlet port opening into the casing et each side-of the stator, and an abutment in the groove between the inlet and outlet ports.

In testimony that claim the foregoing as l my own, I have hereto affixed my signature.
